Abstract

PURPOSE:To connect an incoming call after a callee-side views information on a caller. CONSTITUTION:When the incoming call is detected in ICT 5, CPU 2 connects ICT 5 to REG 8, receives a callee number and a caller number, connects ANT 9 to ICT 5 and transmits the callee number and the caller number to HOST3 through a CH bus 10. HOST 3 reads caller information from DB4 based on the caller number and transmits it to CPU 2. It displays the incoming call on STA 1 of a callee telephone set through LC 6 and displays caller information. STA7 inputs the denial/approval of connection by key depression on the telephone set based on caller information display. HOST 3 transmits connection display to CPU 2 through the CH bus 10 so that a system is set to the call state of STA 7 and ICT 5 when connection is requested based on key information which STA 7 inputs.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call connection system for a call processed by an electronic exchange.

[0002]

2. Description of the Related Art A conventional incoming call connection system is a system in which an electronic exchange dials a personal identification number or the like when making an incoming call connection and automatically connects to a called telephone only when the personal identification numbers match.

[0003]

In the above-mentioned conventional incoming call connection system, the electronic exchange unconditionally automatically connects the incoming call to the called telephone when the personal identification number is dialed. However, there is a drawback that the connection does not necessarily reflect the callee's intention.

[0004]

The incoming call connection system of the present invention utilizes an stored program and data to control an exchange connection of a line accommodated in a central processing unit when an incoming connection is made. Receiving / identifying means for receiving / identifying the calling party number following the called party number and receiving / identifying the calling party number
Transmission means for connecting the announcement device to the telephone set of the calling party when identified, and sending out the calling party number and the called party number of the previous term to the computer controlling the database storing the calling party information. Means, notifying means for notifying the called telephone terminal of an incoming call based on information from the computer, transmitting means for transmitting key information input from the called telephone terminal to the computer, It has a connection / disconnection processing means for performing connection / disconnection processing according to a connection / disconnection instruction from a computer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a diagram showing a state transition in the case of a station line incoming connection in this embodiment.

In FIG. 1, this embodiment comprises a host computer (hereinafter HOST) 3 for controlling a database (hereinafter DB) 4 which stores caller information, and an electronic exchange, and the electronic exchange is connected to a central line. Incoming trunk circuit (hereinafter referred to as ICT) 5 for interfacing and subscriber telephone (hereinafter referred to as S

6, a register (hereinafter referred to as REG) 8 for receiving dial signals from the office line and the STA 7, and an announcement device (hereinafter referred to as ANT) 9 for sending announcement information to the calling party.
And between ICT5 and LC6 and ICT5, LC6 and RE
Switch for connecting G6 and ANT9 (hereinafter SW) 1
And a central processing unit (hereinafter referred to as CPU) 2 for controlling the entire program of the electronic exchange, and the electronic exchange and HOST 3 are constituted by a CPU-HOST bus (hereinafter referred to as CH bus) 1
Connected by 0.

Next, the operation of this embodiment in the case of an incoming call connection will be described with reference to FIGS.

When an incoming call is detected by the ICT 5 (state 1), the CPU 2 connects the ICT 5 to the REG 8 in order to receive the dial signal from the ICT 5 (state 2). After that, the called number and the calling number coming from ICT5 are set to R.
When received by the EG8, the CPU 2 connects the ICT 5 to the ANT 9, and sends the received called party number and calling party number to the HOST 3 via the CH bus 10 (state 3).

As a result, the HOST 3 searches the DB 4 based on the calling party number, reads out the necessary calling party information, and sends it to the CPU 2 via the CH bus 10. The CPU 2 sends the called party telephone via the LC 6 to the called party telephone. The STA 7 displays the incoming call and the calling party information (state 4). When the STA 7 inputs the refusal / acceptance of the connection based on this caller information display by pressing a key on the telephone, this information is notified to the HOST 3 via the LC 6, CPU 2, and CH bus 10 (state 5).

The HOST 3 is based on the key information (rejection / acceptance) input by the STA 7, and when the connection is requested, the STA 3
CH bus 10 to set up a two-party call state of 7 and ICT5
A connection instruction is sent to the CPU 2 via (step 6).

When the connection is rejected, a disconnection instruction is sent to the CPU 2 via the CH bus 10 to send a reorder tone (ROT) to the ICT 5 (state 7). As a result, the CPU 2 performs each processing based on the instruction from the HOST 3.

[0013]

As described above, according to the present invention, the calling party information is notified to the called telephone by the instruction from the computer provided separately from the electronic exchange before the incoming call is connected.
Since the incoming call is connected after determining the intention of the called party, there is an effect that the intention of the called party can be sufficiently satisfied for connection.
